title: Simultaneous determination of seven sulfonamide residues in swine wastewater by high-performance liquid chromatography.
abstract: A HPLC-UV method was used for simultaneous determination of the residual sulfonamides in swine wastewater. Sulfonamides were extracted with ethyl acetate prior to chromatographic analysis. An ODS column was used for separation and UV detection was used to monitor the sulfonamides. Factors that affect the chromatographic behavior and the recovery have been studied. Calibration graphs were linear with very good correlation coefficients (r > 0.9999) from 0.05 to 10 micrograms/ml. The applicability of the method to the analysis of swine wastewater samples was demonstrated.
